摘　　要：近年来,兴隆枢纽坝下河床下切较为严重,一线船闸1000吨级船舶通航保证率不高。为研究二线船闸建设规模,需要根据过闸运量预测,分析既有船闸和新建船闸的通过能力。文章根据过闸船舶统计数据和发展变化的规律,预测了未来过闸船舶的组成。采用离散事件系统仿真方法,模拟船舶随机到闸和排档过程,按船舶随机到达顺序依次过闸,构建了船闸群的系统仿真模型。计算结果表明,兴隆二线船闸近、远期单向年通过能力分别为3198万t、3873万t,兴隆二线船闸有效长度取300 m是合适的。In recent years,the undercutting of the riverbed under the Xinglong Hydrojunction Dam is more serious,and the navigation guarantee rate of 1000-ton ships in the first-line ship lock is not high.In order to study the scale of second-line ship lock construction,it is necessary to analyze the passing capacity of existing locks and new ship locks according to the prediction of the traffic volume passing through the locks.According to the statistic data and the law of development,this paper predicts the composition of the ships passing through the locks in the future.The discrete event system simulation method was used to simulate the random arrival and stalling process of ships,and the system simulation model of ship lock group was constructed according to the random arrival order of ships.The calculation results show that the near-term and long-term oneway annual passing capacity of the Xinglong second-line ship lock is 31.98 million tons and 38.73 million tons,respectively.It is appropriate to take the effective length of the Xinglong second-line ship lock to be 300 m.
